    //UITabBarControl 标签视图控制
    //主要管理没有层级关系的视图控制器
    //1.viewCOntrollers中的所有被管理的视图控制器，都在这个数组中
    //可以通过setter方式形式，去赋值
    //也可以通过下述方法去赋值
    //setViewControls：abinmted
    //setViewControllers :animated:
    //    3. 通过一数组创建完成后， 如果数组中的控制其没有设置
    //    tabBarItem， 则显示一个空的tabBarItem
    // 4. tabBarItem根据自己需求去创建对应的tabBarItem
    // UIViewController的属性（category）
    // 因为：每个视图控制器的tabBarItem都不一样，因此不能设为TabBarController属性
    
    // 创建方式
    // initWithTabBarSystem 根据系统样式创建
    // initWithTitle: image: tag: 根据自定义的图片和文字创建
    // initWithTitle:image:selectedImage:tag： 根据自动以的图片与文字创建，增添选中图片
    
    //badgeValue 角标
    
    //5.如果数组个数过多 （统一使用一种方式去管理）系统会把多余的用统一的方法去控制，建议不要使用
